What if there was a raid for dark souls 1, 2 or 3?
It would drop you in front of some massive large entrance, you would get your team together and would have multiple raid mechanics like wrath of the machine or Vault of glass...
4-6 man teams
Such as players having to spread out and stop special enemies from reaching plates, or obtained in special unique weapons.
Difficult bosses with new innovative mechanics.
Special gear that could only drop from the raid.
And of course the painful difficulty we live from the souls franchise.
It'll never happen but just a fun idea.
